WTF? How did they not notice this was going to be an issue way before now?

They are the least intelligent contractors from my experience with them thus far.

Can you get a wide threshold to match the hardwood and have it installed on an angle like a ramp from upper to lower floors? Be sure and post this photo on their website and give them a review.

Sorry but that is not professional its really a 🤦‍♀️ You can have a carpenter make u a reducer transition piece but the door will need to be cut shorter to accommodate The premade reducer at stores want cover such a large thick transition

Did they REMOVE the old tiles??? This 2" difference is the type of height variation I would expect to see with the old floors still in place.

We just had a couple of tile floors done with all the optional layers and did not end up with that type of thickness. Your contractor should have had a transition solution discussed and decided with you before starting. I think the new tile is a re-do to get the appropriate height. As a last resort, Schluter makes some adjustable, metal transition strips designed for high differentials, but they will look too industrial for your taste in that location, and without a height correction, it will be a trip hazard any way you do it.

"They are the least intelligent contractors from my experience with them thus far."

Now that they have messed you up good, what is there thoughts to make this acceptable?

That middle front tile should be re-cut in any case; it looks to have a poorly cut sharp corner jutting out in just the right place to catch a toe, yikes. This is horribly unworkmanlike, and you have every right to ask for a complete re-do of the project.

I had a similar situation in an old house. The height differential was 1.25" between my bathroom (tile) and bedroom (wood). I couldn't find anything available commercially, so I decided to make my own reducer. I bought a piece of oak that was 1 1/8" tall and 3" wide and then took it to a wood shop where they cut it on the diagonal to make it go from 1 1/8" tall on one edge to 1/4" on the other edge. I sanded it down to smooth it, stained and finished it, and then glued it to the floor. I did have a quartz threshold in the bathroom door frame that was level with the tile, so the wood reducer goes between the quartz and the wood floor. It works really well and I feel that it's much safer than having such a large step up. I'll bet you could do something similar.

I am going through this right now. Contractor said the house is not level in the kitchen. In order for the appliances, cabinets etc to sit and be placed properly, the floor has to be leveled. How does that sound to you all?

Yeah kind needs to be at least flat, most flooring all requires this as well.

It is common for floors to be unlevel, but for cabinetry and countertop placement it becomes a nightmare for shimming unless the floor is as level as possible. I had to have my slab ground in places before kitchen tile was placed during my recent remodel.

That's not up to code, either you hired a friend to do it and they screwed you or I would report them to your county

I’m sorry to say that my husband and I find ourselves in an almost identical situation. What did the contractors wind up doing? I hope you don’t mind me asking, but are you at peace with the outcome? Trying to weigh the pros and cons of ripping out-and only possibly being able to lower the floor by half the height-versus designing a saddle/transition that minimizes the step as much as possible.
